The OEM’s choice
The SI range of isolators was specically developed for arduous DC disconnect applications and SI isolators are used by many of the largest
Solar Inverter manufacturers in the world.
The new SIM range features the same independent trigger ratchet switching mechanism delivering arc extinguishing times of <5ms (3ms
typical). Specially designed internal arc cooling chambers control temperature rise and increase safety while knife edge contacts increase
reliability and prolong electrical life.
All this along with a 35% reduction in size makes the SIM Series the ideal next generation choice for OEMs globally.
The next evolution in DC isolation
When IMO rst launched its SI Series DC isolator in 2009, little did it know that the SI would soon become the safety component of choice for
many of the largest solar inverter manufacturers and installers around the world. Today, with over 6 million installations and ZERO reported
electrical failures*, the SI Series has proved itself more than capable of handling the most demanding DC switching applications.
The NEW SIM represents the next evolution in DC isolation oering all the benets of its big brother in a compact, high reliability package. With
a 35% reduction in cubic volume, reduced front plate “real-estate”, increased ratings and extended mounting options, the SIM is packed with
features. Yet it retains the high reliability technology of the current SI Series including knife edge contacts, high speed operator independent
switching mechanism and full arc control with guaranteed suppression time.
The NEW SIM represents the next step in meeting the global demand for high reliability, compact and competitive DC safety switching solutions.
Safety as standard
In solar installations, the DC isolator is like a vehicle air-bag. It is rarely called upon but, when required, carries a huge responsibility. So it’s
good to know that the IMO SI is safeguarding millions of solar installations around the world, without a single reported electrical failure.
Not surprising considering the product carries all the most important approvals including UL508i. In fact the IMO SI range of solar isolators
have been tested by some of the most rigorous examiners and OEM manufacturers in the world, passing with ying colours every time.
Smaller... and better
When buying IMO you can be assured of the level of quality and reliability of our products. The SIM is no exception, and just because we have
managed to squeeze everything that went into our market-leading SI range into the new SIM’s compact body, we haven’t compromised on
reliability. In fact, we have increased the overall ratings and extended the mounting options.
